In order to book a walk-in, start by navigating to the Admin Panel. 

Then choose the amount of blocks to book (every block is 30 minutes).

After selecting your options and players, you can use the "Add to Purchase" button to include a line item, allowing you to add more item options if needed.

Additionally, you can assign a customer by clicking on the "Anonymous" button—this gives you the option to either create a new customer profile or simply add an existing customer.

Once everything is set up, you can proceed with charging the customer as usual.
